Facebook CEO Mark Zuckerberg 'checked in' at IIT Delhi for the much-awaited Townhall on Wednesday, where he fielded questions ranging from those about Facebook's Internet.org initiative to tips for blocking CandyCrush requests.

The Townhall Q&A with Zuckerberg kicked off at 12 pm IST at IIT Delhi on Wednesday.

Students and professionals pitched their questions to Mark about how his team built Facebook to whether Facebook supports net neutrality, while many also sought personal advice from him on how to deal with challenges and mistakes.

You can check all the questions asked during the Townhall and Mark's responses below .

UPDATES:

1.12 pm IST: The Townhall with Mark Zuckerberg has ended.

1.09 pm IST: Can we have any features to help locate missing people similar to the Safety Feature?

We have a programme in certain areas, where we put up a photo of a missing child on the newsfeed, and it has helped locate many children in the last year.

1.07 pm IST: Are there any decisions during the early days of Facebook that you regret?

I made many mistakes - technical mistakes, product mistakes. The thing to focus on is not which mistakes you should avoid, but to do something good that can give you the strength to power through these mistakes.

1.00 pm IST: Can you share an anecdote of how you dealt with being demoralised?

The reality is that as strong as any individual is, no one person can deal with all the challenges, and one way to deal with that is to have partners and co-founders who can keep pushing each other. There is data that shows that companies that have several co-founders are likely to be more successful.

1.00 pm IST: What according to you are the elements of an ideal start-up?

Every good company started with someone who cared about something. Building a company is hard, and you do need to care. You should start a company when you think your work is pretty good.

12.54 pm IST: What was your Eureka moment for creating Facebook?

There is no Eureka moment, or a moment of revelation that Facebook was going to be awesome. You start off building something you care about, and I had built it to be connected to my school community.

I assumed someone like Google or Microsoft would build something like this for the world. We just kept doing one thing at a time and kept going.

Many people thought it wouldn't make any money. But pretty soon, we had a service bigger than many others.

12.52 pm IST: Did people recognise you when you visited Taj Mahal?

The Taj Mahal is great, even better than what it looks in pictures. There are monuments built for governments or for military victories. But the Taj is a monument of love, and I am glad I got a chance to go.

There was one girl trying to take a photo of me and fell into a bush. I gave her a pat on the back and told her to be careful.

12.44 pm IST: Does Internet.org support net neutrality fully?

Absolutely. We do a lot to support net neutrality. In terms of regulation, countries are figuring out what rules they want and we are supportive of that.

In terms of open platforms, there are reports that we are using only a small set of services. But what we are really trying to do is to use Free Basics so that any developer who can give low bandwith services for free can be zero-rated. That has been powerful, and provides a neutral platform without any filters.

If an operator is trying to advantage their own service, it hurts people, and we want net neutrality.

But those who advocate against zero-rating, I look at a student who wants free access to the internet for her studies, who gets hurt by that?

Around the world, all the regulations are honouring this principle, prioritising zero-rating necessary to connect everyone to the Internet.

Facebook, Internet.org support net neutrality 100% but we also need to push for access.

We have a moral responsibility to look out for those who do not have access to the Internet.

12.42 pm IST: What superpowers would you like to have and how will you use it for the betterment of the world?

With technology, we can build superpowers for people around the world. With Oculus, we are helping people teleport, even to places impossible to go to.

12.37 pm IST: How can Facebook help illiterate people?

Our mission is giving people the power to share and making the world more connected. We have a few big projects, and the graduate rate in the city where we have tried it has increased in just five years.

Internationally, we are creating new types of schools in Africa and also want to bring it to India. For people who don't have access to good schools, they can be helped by getting access to education material online.

12.32 pm IST: Facebook is investing a lot in Artificial Intelligence (AI). What are your plans with it?

We have this goal that in five to ten years, we want to build computer systems that can conceive better and recognise things, and have a better sensory system than humans. But we are far off from having computers that are smarter than people.

It is more about increasing intelligence. AI can help visually-challenged people know what is in a photo by reading out the description of the photo.

Second example is about the Safety check for earthquakes. Right now, this is a feature for people to know who is safe. In the future, with satellites, we can identify who needs help in any area.

12.30 pm IST: Mark speaks about the baby he is expecting with his wife Priscilla Chan.

My wife and I are expecting our daughter, and we are excited. I want to take a video to share that experience with my family and friends who may not be able to come. That is why we are moving towards richer and richer communication.

12.25 pm IST: Third question: How do we stop getting CandyCrush requests?

I saw that this was the top-voted question on my post. We have prioritised to bring out a solution to this problem.

12.22 pm IST: Second question - "How do you plan to connect to those who are not on Facebook or those who do not have access to Internet access?"

Internet.org is a programme live in 24 countries and 15 million people around the world have access to the Internet under this initiative. I see some cynical reporting, but if you don't think that's good, I want to know what is.

In India, almost a million people have access to the Internet due to Free Basics services. In the areas where Free Basics is available, Internet growth rate has doubled.

12.17 pm IST: First question to Mark - "Why are you showing so much interest in India?"

India is the world's largest democracy. First, there are already more than 130 million people in India who use Facebook. Having the ability to hear how we can improve is a thing we need to do for the community.

Secondly, there are a billion people in India who do not have access to the Internet. Those who have access take it for granted.

It is a tool that provides vital infrastructure for your lives. People who do not have access are robbed of the opportunity, and that's why I care about India. It is our second biggest community in the world. And we really want to get the next billion people online.

12.15 pm IST: Zuckerberg mentions the earthquake that hit Afghanistan and Pakistan and also sent tremors in India. "When there is a disaster, you want to know if people you know are safe. We have activated the safety check, and more than three million have marked themselves as safe," he said.

12.14 pm IST: "India has a 130 million people, the second biggest country to use Facebook. It is really important to hear from you today," Zuckerberg says.
